DIRECTIONS  FOR  DYEING 


ACID  COLORS 


Nos.  401-435 


These  are  dyed  in  a gum  soap  bath,  broken  with  Sulphuric  Acid. 
With  the  Eosine  brand  it  is  advisable  to  employ  Acetic  Acid. 

The  Diamond  Fast  Purples  should  be  dissolved  with  a small  per- 
centage of  Ammonia,  which  is  to  be  added  to  the  powder  and  boiling 
water  poured  over  it. 


BASIC  COLORS 


Nos.  436-446 


These  colors  are  generally  dyed  in  a gum  soap  bath,  broken  with 
Acetic  or  Sulphuric  Acid;  Sulphuric  Acid  is  used  especially  when 
dyeing  in  combination  with  Acid  colors. 


SULPHON  AND  DIRECT  COLORS 

Nos.  447-452 

These  are  dyed  in  the  same  manner  as  the  Basic  Colors — Acetic 
Acid  is,  as  a rule  effective  enough  to  exhaust  the  bath. 


ALIZARINE  AND  CHROME  COLORS 

Nos.  453-455 

Add  the  well  dissolved  color  and  10-20%  Acetic  Acid  to  the  Dye 
Bath  at  a temperature  of  100-120  degrees  Fahr.  Bring  slowly  to  boil 
and  boil  for  one  hour.  Should  the  bath  not  exhaust  sufficiently  add 
more  Acetic  Acid — after  this,  treat  with  Bichrome  for  ?4  hour  in  a 
fresh  bath,  boiling  gently: — rinse,  soap  and  acidulate. 


CHROME  MORDANT 

No.  456 

Dye  in  a gum  soap  bath,  broken  with  Acetic  Acid.  Work  for  k \ 
hour  at  120°  Fahr.,  warm  up  to  195°  Fahr.  in  J4  hr.,  and  dye  at  this 
temperature  for  1 hr.  Rinse,  soap  at  the  boil  and  acidulate. 

SULPHUR  COLORS 

Nos.  457-462 

Dissolve  with  the  same  amount  of  Sodium  Sulphide  Crystals  with 
the  addition  of  the  same  amount  Glucose.  Add  this  solution  to  the 
Dye  Bath  at  180-200  degrees  Fahr.  then  add  30-60%  Glaubersalt,  and 
finally  add,  shortly  before  entering  the  goods,  Bicarbonate  of  Soda, 
corresponding  to  about  half  the  weight  of  the  color.  Work  for  aboul 
half  an  hour,  then  squeeze  out  the  silk  and  expose  to  the  air  for  a 
short  time.  Rinse  well — soap  at  the  boil  and  acidulate  with  Acetic 
Acid. 


DEVELOPED  COLORS 

No.  463 

These  are  dyed  in  the  same  way  as  Direct  Colors, — rinsed  well  and 
diazotised  cold  for  15-20  minutes  with — 

2l/2%  Nitrite  of  Soda  (Dissolved  in  water) 

7}4%  Hydrochloric  Acid  (32  degrees  Tw.) 

The  goods  are  again  rinsed  and  developed  for  15-20  minutes  in  a 
cold  bath  with  the  developer,  Beta  Naphtol.  In  order  to  dissolve  the 
latter,  use  34  the  amount  of  Caustic  Soda  to  the  weight  of  the  Beta 
Naphtol.  After  developing,  rinse  and  soap  if  necessary.
